摘要
对某石拱桥的原设计、病害状态以及加固后的三种状态进行了结构模拟分析,得到了三种不同状态下各自的可靠度和受力情况,从而得出采用套拱法加固该类型的桥梁具有良好的加固效果,具有较为广阔的应用前景。
Through the three model analysis with one arch bridge in the stage of initial design, disease status and strengthened, Ⅰ got three different confidence level and stress in the differem steps. And from that, Ⅰ concluded that stone arch bridge with hcoped strengthening technique can get good result.
